Composed of three magnification specimens attached firmly to a scanning microscope specimen mount. One specimen is 400 mesh copper screening for low magnification work. The middle specimen is a 15,240 line per inch grating for the high magnification range. The third specimen is a 1,500 mesh nickel screening for the middle magnification range. 50 mesh screening is placed over entire grating for strength. This composite specimen is both a time and space saver. Measurement charts and instructions for use included.

Replica specifically made for SEM use is taken from a ruled diffraction grating with two sets of lines ruled at right angles to each other. There are 54,864 lines per inch in both directions. A 50 mesh screen is placed over entire grating for strength. Useful for magnification determination, detection and measurement of lens distortion, and the determination of the degree of fore-shortening in an image, as a function of specimen tilt. Measurement chart and instructions included.

Please specify the type of specimen mount required.
